+1 to what John says. Also over time the crown will wear just from the gas cutting effect of the powder. That’s why I don’t like a basically flat crown right at the edge of the bore. Cut a chamfer at the edge of the bore in addition to what ever style of crown you use (flat style, 11 degree, stepped recess or sporter etc…)

While I agree that this is a useful piece of knowledge, I’ll add that we have seen crowns that were bad that would pass the Q Tip test. This has been especially true in barrels with barrels that have had a fair amount of shooting. It seems that the shooting and cleaning might round off burrs (eventually) but there can still be problems from improper crowning.

Used this just a little less than a jillion times, couldn’t help the jag (pun?) Larry and by the way your products are great! Great tip!

Another thing you can do is push a patch on a jag to within 1-2 inches of the muzzle. Any light shined in then will reflect evenly off the rifling and show copper or other issues.
